Description

Seleno-L-methionine (CAS 3211-76-5) integrates into selenoproteins via methionine salvage pathways, enhancing antioxidant defense mechanisms in mammalian cell cultures under oxidative stress conditions.

Application

Seleno-L-methionine (CAS 3211-76-5) drives protein labeling for single wavelength anomalous dispersion phasing by incorporating selenium into nascent polypeptides with high fidelity. This enables precise structural determination of macromolecular complexes. Researchers leverage it to track selenium metabolism and assess developmental toxicity in Japanese Medaka embryos, while also monitoring selenium status in pregnant long-tailed macaques.
